This rapid action is due to the multiple in the accompanying drawing, in whichthreads 12 and 13.

The teat 29 also forces the spring pressed ball valve 36 away from its seat to permit the flow of the lubricant into the receptacle.

In Figures 4 and 5 we have shown a modified form of our invention wherein the plunger 14 is provided with a lower threaded extension 40 having a. reduced bore 41 into which extends the shank 42 of a pilot 43. The said pilot 43 has an endrecess 44 similar to the recess 27 providing a central teat 45 and an outer flange 46` between which there is inserted a washer 47 to contact with the nipple 25 and form a leak-proof joint' when the device is in operation. A tubular casing 48 is screw threadedly secured to the plunger extension 40 and maintains the pilot in place. An offset opening 49 in the said pilot permits grease -to be forced therethrough to the receptacle 20. It desired the casing48 may be provided with a ange50 to enter the groove 24-a of the disc 24. The shank 42 of the pilot 43 may be atteued as at 51 so that the grease may easily reach the opening 49. In this form of our invention the pressure of the grease acting upon the shoulder 52 will tend to hold the pilot tightly against the receptacle 20 to form a leak proof joint.

From the foregoing it will be seen that we have provided a quick acting leak proof nozzle for a lubricating device, adapted to be readily coupled with or secured to a lubricator receptacle for automobiles and the like.

Having described our invention what we claim as new and desire to secure by Letters Patent is:

1'. A nozzle adapted to be secured to a pressure lubricating device, comprising a barrel having an internal multiple thread, a screw threaded plunger rotatably mounted therein and having a bore in communication with the pressure device, a grease receptacle having a central bore and an annular groove therein, and an end on the plunger dapted to enter the said groove when the said plunger is rotated to bring the bore therein into operative communication with the central bore. f

l 2. A nozzle adapted to be secured to a pressure lubricating device, comprising a barrel having lan internal multiple thread, a multiple screw threaded plunger rotatably` mounted therein and having a bore in communication with the pressure device, a grease receptacle having a central bore and an annular groove'therein, and an end on the plunger adapted to enter the said central bore and groove.

3. A nozzle adapted to be secured to a pressure lubricating devic and lubricatcr receptacle, ccm= prising a barrel, a plunger having a bore in communication with the pressure device and lubricator receptacle, means on the said barrel and plunger to produce a. relative sliding and .rotating movement between the said parts, a grease receptacle having a central bore and annular groove therein, and an end on the plunger adapted to enter the saidgroove when the bore in the plunger is brought into direct communication with the central bore in the receptacle.

4. A nozzle adapted to be secured to a pressure lubricating device, comprising a barrel, a plunger having a bore extending the entire length thereof and in communication at one end with the pressure device, screw thread means on the said barrel and plunger to produce a relative sliding and rotating movement between the said parts, a grease receptacle having a central bore and annularly grooved ange, and an end on the said plunger adapted to enter the said receptacle bore and groove.

5. A nozzle adapted to be secured to a pressure lubricating device, comprising a barrel', a plunger having a bore extendingthe entire length thereof and in communication at 'one end with the pressure device, screw thread means on the saidbarrel and plunger to produce a relative sliding and rotating movement between the said parts, a grease receptacle having a' central bore and annularly grooved flange, a pilot at the other end oi the plunger bore, the said pilot being provided with a bore in communication with the plunger bore, a teat on the pilot adapted to enter the grease receptacle, a shouldered shell for maintaining the pilot in the plunger, and a ange at' the end of the said. shell to enter the receptacle groove.

6. A nozzle adapted to be secured to a pressure lubricating device and lubricator receptacle, comprising a barrel having a cutout at the bottom end thereof, a plunger adapted to be shifted longitudnally by rotary motion mounted in the sa'id barrel and having a bore in communication-at one end with .the pressure device, a perforated pilot operatively mounted at the other end of the said bore, a grease receptacle having a bore in communication with the plunger bore, a disc on the said receptacle for seating and coupling engagement with the barrel cutout, means for maintaining the-pilot in the plunger bore, and the end of said plunger constructed for engagement with the said disc to produce a grease tight joint.
